Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (1S,2S,4R)-2-Bromo-1-isopropyl-4-methylcyclohexane.
(1S,2S,4R)-2-Bromo-1-isopropyl-4-methylcyclohexane (CAS 87161-57-7) is a high-purity analytical reference standard with the molecular formula C10H19Br and a molecular weight of 219.16 g/mol.
Based on its molecular formula C10H19Br, (1S,2S,4R)-2-Bromo-1-isopropyl-4-methylcyclohexane contains bromine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 219.16 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
